Description
Technical field
The present invention relates to field of nonwoven fabric technology, more particularly to a kind of polytetrafluoroethylfilament filament nonwoven that method is split based on film
Cloth and its preparation technology.
Background technology
The material for preparing of simple tension film is ultra-high molecular weight polyethylene, PTFE, polypropylene, PPS (polyphenylene sulfide), P84
(polyimides), wherein, PTFE is the english abbreviation of polytetrafluoroethylene (PTFE), is the king of plastics generally acknowledged in the world at present, with anti-
The advantages of ultraviolet radiation, resistance to chemical attack, wearability, polytetrafluoroethylene fibre chemical stability is fabulous, and corrosion resistance is better than
Other synthetic fibers kinds；Fiber surface has wax sense, and coefficient of friction is little；Meanwhile, also with preferable against weather and warp resistance
Property.
Non-woven fabrics is defined as non-weaving cloth again, is made up of fiber orient or random, is environment-friendly materials of new generation,
With moistureproof, ventilative, flexible, light weight, not combustion-supporting, easy decomposition, nontoxic nonirritant, rich color, cheap, capable of circulation
The features such as using again.As adopted polypropylene (pp materials) pellet for raw material, Jing high-temperature fusions, spinneret, paving guiding principle, hot pressing are batched continuously more
One-step production is formed.Cloth is called because of the outward appearance with cloth and some performances.Realize in the U.S. from nineteen forty-two early start
After industrialization production, because it has, low cost, products application big compared with conventional woven cloth simple production process, yield extensively etc.
Feature, nowadays, it has also become emerging field with the fastest developing speed in textile industry.Non-woven fabrics can be divided into by processing method difference：
Spun-bonded non-woven fabrics, spunlace non-woven cloth, heat seal non-woven fabrics, wet nonwoven fabrics, needle punched non-woven fabrics etc..Non-woven fabrics has many functionally
Excellent properties, purposes is extremely extensive, can be divided into according to its purposes：Clothes non-woven fabrics, furniture decoration/household non-woven fabrics,
Non-woven fabrics for medical healthcare, filtering material non-woven fabrics etc..
The cloth of method shaping, manufacture are tangled etc. more than the manufacture of existing non-woven fabrics using the direct hot melt adhesive of chopped fiber, machinery
Process is relatively easy, low cost. but the binding site of hot melt adhesive only occurs in fiber intersection points, advantage be have elasticity well and
Fluffy degree, has the disadvantage the cutting or directly purchase of chopped fiber, transport and personnel cost is increased, due to the spy of chopped fiber itself
There is the defect of fiber head, uneven surface in point, the non-woven fabrics prepared.
In prior art, splitting method film by film and split the filament fiber for can not make non-woven fabrics, for manufacturing woven bag etc.,
While how film is split the filament fiber manufacture non-woven fabrics for, filament fiber is not cut off, be non-woven fabrics directly into the method for cloth
The new trend of technical field.
The content of the invention
For defect present in prior art or deficiency, the present invention is innovatively proposed a kind of splits the poly- of method based on film
Tetrafluoroethene continuous yarn non-woven fabrics and its preparation technology, one-shot forming manufacture, can overcome non-woven fabrics fastness in prior art it is poor,
The defects such as complicated process of preparation, making the overall dynamics of the polytetrafluoroethylfilament filament non-woven fabrics for splitting method based on film strengthens, with good
